Disk Archives --- Browse [IBM PC](pc/) and [Challenger 1P](c1p/) disk images. ### PCjs Disk Image Formats PCjs works best with disk images in a **JSON** format, to save conversion time, so that's the only disk image format you'll find on the PCjs website. To convert any of our **JSON** disk images back into an **IMG** file, you can use the DiskDump API with the *format* parameter set to `img` instead of `json`. For example: http://www.pcjs.org/api/v1/dump?disk=/disks/pc/dos/ibm/2.00/PCDOS200-DISK1.json&format=img In fact, when browsing the disk archives, the PCjs web server automatically provides "onclick" handlers for links to JSON-encoded disk images, which will invoke the API for you. See **Creating PCjs-Compatible Disk Images** in the [PCjs Documentation](/docs/pcjs/) for more information about supported disks and formats.
